Close preset messages popup before closing the status window. Otherwise GTK will freeze when the window is closed after the inactivity timer has expired. Fixes #4052

* configure --help to show disable message when --disable-FEATURES (we can use disable or enable
for each one AFAIK)
* Add dbus compile time requirement to README.html

URLs like (http://myFoobar.org) and http://en.wikipedia.org/wiki/Mornington_Crescent_(game) are now correctly detected.

Do not update metacontacts when nothing has changed. Fixes sending metacontact info to server when we expand a groupchat.

 * Do not double escape group names
 * Try to remove SelfContact on disconnect only once
 * Do not show minimized groupchats which were minimized after disconnect
 * Always reset group expand state after adding a contact to roster.

don't try the old (XEP-018) way to go invisible. It's not XMPP complient. That prevent to show the we are invisible but we are not. Fixes #4012

don't think connection to server failed when only first connection attempt failed when creating a new account

when we right click on a word in conversation textview, even if it's not selected, show actions menuitem to look in dictionary and so on. see #2874

when we are disconnected from server, we then try to reconnect only with the type (tls, ssl, plain) that worked first time. Fixes #3896

 * Don't traceback when another resource of us is moving contacts to new/different groups.
 * Always refilter all involved groups.
 * It is now possible to not update contacts severside when using add/remove_from_groups

* Added NS_RECEIPTS to protocol namespace list.
* Show our support of XEP-0184 in caps.
* Added a big, fat warning to get_contact as this does not work as
  expected.
* There was some strangeness in our XEP-0022, it added an id tag to
  the x tag, which isn't mentioned anywhere in the XEP. And for some
  strange reason, that id even was the same all the time.
* Fixed a typo.
